LOGIQ E9 Security (continued)
3-38
We have worked diligently to develop a combination of the
safety measures above and the security standards of Windows
Embedded Standard 7 to provide a degree of safety against
Viruses, Worms, Trojan Horses, etc., especially for a system
used in a professional hospital grade networking environment
that also typically features its own sufficient safety measures.
Finally, a few points as to why we do not use Anti-Virus software.
The main reasons for not doing so:
• Every Virus scanner is constantly active in the background.
Due to the software-intensive operating system of the
Ultrasound scanner, all computing resources are required
for normal operation of this device. Anti-Virus software
activities would have a negative impact on the system
performance.
• The operating software of a medical Ultrasound system is
part of an FDA-cleared medical device that requires a
specific release process. Any update of the Anti-Virus
software would mean a change of the system software.
Such change would require an extensive release and
validation process to help ensure that the Anti-Virus update
does not have any impact on the system software
performance and stability.
